Pandanite is a minimalist implementation of a layer 1 cryptocurrency similar to Bitcoin. It is designed with utmost simplicity and user friendliness in mind and is written from the ground up in C++ — it isn't yet another re-packaging of existing open-source blockchain code (where's the fun in that?!).
Pandanite is minted by miners who earn rewards. Mining payments occur using the thwothirding algorithm, which yields a total final circulation of ~99.1M PDN:
- 6647477.8490 PDN carried over from previous forks distributed
- 50 PDN per block at Heights 1 to 515736
- 50*(2/3) PDN per block from blocks 515737 to 515736+666666
- 50*(2/3)^2 PDN per block from blocks 515736+666667 to 515736+2*666666
etc.
Block reward changes are more often and have less impact compared to halving:
The payout curve is smoother in twothirding compared to halving:
Pandanite is written from the ground up in C++. We want the Pandanite source code to be simple, elegant, and easy to understand. Rather than adding duct-tape to an existing currency, we built Pandanite from scratch with lots of love. There are a few optimizations that we have made to help further our core objectives:
- Switched encryption scheme from secp256k1 (which is used by ETH & BTC) to ED25519 -- results in 8x speedup during verification and public keys half the size.
- Up to 25,000 transactions per block, 90 second block time
Windows: Windows is not currently supported as a build environment. You may run the dcrptd miner to mine Pandanite

To compile the miner run the following command:
make miner
You will also need the keygen app to create a wallet for your miner:
make keygen
To compile the node server:
make server
To compile a simple CLI tool that lets you send PDN:
make cli
For a separate, interactive GUI wallet see https://github.com/pandanite-crypto/pandanite-wallet
Start by generating keys.json.
./bin/keygen
Keep a copy of this file in a safe location -- it contains pub/private keys to the wallet that the miner will mint coins to. If you lose this file you lose your coins. We recommend keeping an extra copy on a unique thumbdrive (that you don't re-use) the moment you generate it.
To start mining:
./bin/miner
To host a node:
./bin/server
Some server running args:
-n (Custom Name, shows on peer list)
-p (Custom Port, default is 3000)
--testnet (Run in testnet mode, good for testing your mining setup)
Full list of arguments can be found here: https://github.com/pandanite-crypto/pandanite/blob/master/src/core/config.cpp
To send PDN to another address (run with --local flag if the server you want to use is listening on localhost):
./bin/cli
Pandanite is pre-built for amd64 and arm64 with GitHub Actions and distributed with the GitHub Container Registry
with docker
docker run -d --name pandanite -p 3000:3000 -v $(pwd)/pandanite-data:/pandanite/data ghcr.io/pandanite-crypto/pandanite:latest server
docker logs -f pandaniteYou can follow the progress of server sync from http://localhost:3000
Running with docker-compose is recommended to easily add more options like cpu usage limits and a health checks:
